The drilling of an exploration well aims at confirming the accumulation of petroleum. Thus, a reservoir can only be confirmed when drilling through it. Technology has improved in the exploration phase but there is still uncertainty when it comes to determining the volume in the appraisal phase. It is difficult to know if the reservoir is worth developing.
The true size of the field can only be estimated. Usually, additional wells are drilled in order to measure the volume. It is time consuming and expensive due to the size of the operation. The environmental impact can be large both in terms of energy consumption during the operation and in terms of intervention in the seabed. With Hydrophilic technology the job can be done easier, quicker and more environmentally friendly.
With hydrophilic technology, you’ll be able to find the oil/water contact without having to drill additional wells. This will significantly shorten the appraisal phase and limit the enviromental impact of developing an oil field.
